Android 应用程序不工作,不幸的是,XML已停止错误

Android 应用程序不工作,不幸的是,XML已停止错误,android,eclipse,error-handling,Android,Eclipse,Error Handling,我编写了以下代码来解析此xml: 但当我运行它时。。。它说应用程序停止工作,我无法找出原因。。。请帮忙 代码是: xmlActivity.java xmlParser.java 不能在活动线程中执行像HttpRequest这样的慢速操作。您必须将它们放在单独的线程异步任务中。这是谷歌提到,但我失去了来源,我很抱歉 您应该尝试创建一个异步任务,下面是您应该如何尝试: public class GetSoigneurInfoTask extends AsyncTask<Document, In

我编写了以下代码来解析此xml:

但当我运行它时。。。它说应用程序停止工作,我无法找出原因。。。请帮忙

代码是:

不能在活动线程中执行像HttpRequest这样的慢速操作。您必须将它们放在单独的线程异步任务中。这是谷歌提到,但我失去了来源,我很抱歉

您应该尝试创建一个异步任务,下面是您应该如何尝试:

public class GetSoigneurInfoTask extends AsyncTask<Document, Integer, Document>                 //Le même code s'applique pour presque tout sauf onPostExecute()
{
    Document doc;
    String xml;
    String url;

    public GetSoigneurInfoTask(String URL)
    {
        url = URL;
    }

    protected Document doInBackground(Document...params)
    {
        xml = XmlFunctions.getXML(url);                                                         
        doc = XmlFunctions.XMLfromString(xml);
        return doc;
    }

    protected void onPostExecute(Document result)
    {
            if(result != null)
        {
            NodeList nodeList = doc.getElementsByTagName("RootTag");                                //Crée une liste avec les elements sous soigneur
            for (int i = 0; i < nodeList.getLength(); i++) 
            {
                Node node = nodeList.item(i);
                if (node.getNodeType() == Node.ELEMENT_NODE) 
                {
                    Element element = (Element) node;
                    NodeList nodelist = element.getElementsByTagName("childTag");
                    Element element1 = (Element) nodelist.item(0);
                    NodeList fstNm = element1.getChildNodes();
                    soignTemp = fstNm.item(0).getNodeValue();

                }
            }
        }
    }   
因此,您可以在doInBackground中调用您的方法,并在onPostExecute中完成所有与UI相关的操作


希望这有帮助

请为您的错误添加Logcat输出:异常堆栈跟踪等。我无法获取什么意思您不能在活动线程中执行类似HttpRequest的慢速操作我在另一个URL上执行此操作,它工作正常,仍在工作,但不在此URL上。当我尝试在浏览器中打开您的URL时,我在此处找到了它表示:缺少参数:xmin。是的,这是链接你真的能从中得到信息吗?XML文件应该如下所示。我的意思是他们展示了很多例子,但我相信这些都是不可解析的。如果我错了,请纠正我!
